$l llbllhllhtGi ltllAUl-llll t En SPECIFICATION forming part of Letters Patent No. 780,300, dated Januaryv 1'7, 1905. Application filed February 29, 1904:. ferial No. 195,740.

jZo/M/ 'm/wm it may concern:

Be it known that I, Jenn Nnwsonin, a subjcct oi the King of Great Britain. and aresident of Holyoke, in'the county of Hampden and State of Massachusetts, have invented certainnewandusefull mprovementsin Spinningcommon textile spindle-driving bands which run around a main drum and the individual whirls of the spindles and which, as well known, not only become stretched and of uncertain tension. but too frequently break, rendering the machine temporarily inoperative.

The object of this invention is to make use of friction-disks one series of which are carried by the spindles, While the other series carried on a common shaft to which rotation is imparted, the latter. disks being in frictional contact with those of the spindles; and it is the objectoi' the invention to acquire an arrangement of the disks whereby, without any especially nice construction and adjustment, the frictional bearing for the d riving' may be constantly uniform for all of the spindles. 1

Another object of the invention is to render the driving arrangements susceptible easily of reversal; and a still further object is to so construct, arrange, and combine the parts that the whole driving apparatus is oi 'extreme simplicity and comprises but a minimum of essential components. i

The invention consists in the combination and arrangements of parts and the construction of certain of the parts, all substantially as hereinafter described, and set -forth in the claims.

1n the drawings, Figure l is an end eleven tion, with parts in section, of the carriage portion ofa mule, showing the improved spinrile-driving mechanism. Fig. 2 is an elevation of thesame as see at the left at right ing' the driving-shaft carrying a plurality of friction-disksand in section showing the 1s a view in detail sh0wr l l l i l l i l g the lengths of the manner of engagement of the disks'ot the shaft.

Similar characters oi reference indicate corresponding parts in all of the views. In the drawings, A represents the carriage of a mule, provided on which are upper and lower rails B and C, the upper rail having a series of journal-openings a therein, through which are journaled the lower portions of the spindles i) for carrying the bobbins. these spin dles being made without whirls and have near theirlower ends each a friction-disk E aiiiired thereto, each of which disks, as shown, being of frusto-conical form downwardly tapering, and below the lower end of each of these disks E is a step end or journal projection F, which has bearing for rotation in an upwardly-ope ing' socket Z) in the upper part of a curved bracket i the inversely-turned member (Z of which 18 screwed-or otherwise secured to the lower rail (1.

,of disk s'M may bev adjusted and aflixed with a'nic'ety on the shaft J, so that all of the disks will simultaneously'be in frictional contact against the spindle-disks, provisions as represented in 'Fig. 3 are practical and very desirable, the same including a spline-groove Win the shaft J, in which a spline 0 for each disk M engages, and a spiral spring q, applied between an abutment or shoulder 2% on the shaft and the side of the disk. By endwise shifting the shaft J through the shipper-lever described the disks M may have either at the right-hand sides of the spindle-disks or relatively at the lefthand sidesof such disks to correspondingly desired, and when the shaft J is, for instance, moved l leftward to bring the shaft-carrier disks M l to work at the right-hand sides of the spindledisks the collars or abutments t on the shaft will crowd the spiral springs relatively at the right-hand sides of the disks M to exert a 'leftw'arddirection against such. disks, so that they will be under a yielding spring stress,'the degree of which for proper frictional driving may be determined by the constructor in the selection of a spring'of appropriate potentiality, and of course as those springs tothejrightward of the disks M are brought into abnormal compression those at theleft of'such disks react and are of with the upper and lower rails, and a series of rotating spindles extending through the upper rail and provided therebelovi with a seprojections at their extremities below the disks, of a series of brackets supported on the lower rail and having step-sockets intheir upper portions receiving therein the spindle journal-steps, a shaft arranged right angularly to the lengths of the spindles, and having thereon a series of friction-disks engaging the spindle-disks, and means for rotating said shaft.
